BOTTLE-SEALING DEVICE.

Specification of Letters Patent.

Patented Sept. 3, 1907.

Application filed May 4,1907. Serial No. 371,730.

To all whom it may concern:

Be it known that I, WILsoN BAILEY, a citizen of the United States, residing in theicity of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Bottle-Sealing Devices, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification. I

My invention relates to that class of bottle sealing devices applicable more particularly to the closing of large-mouth bottles such as pickle jars and the like, and it comprises a hard metallic cap having a crown with a narrow flange rim and an additional but integrally connected rim transversely sectioned, the latter adapted to be sealed on the head of a bottle having a relatively projecting annular rib or shoulder below the lip thereof, and capable of being removed therefrom by severing the integral connection between the flanged crown portion and the transversely-sectioned additional rim.

Heretofore it has been proposed to make a sealing device of a crown portion and a transversely sectioned locking rim or ring, with or without an integrally connecting strip between them rearward of the edges of the sectioned rim, and with a tongue proceeding from the crown portion, the tongue being slotted to receive projections or hooks on the two edges of the sectioned locking rim; but the slot and hook principle of securing the ring to the crown in locked position on the bottle is objectionable, principally because of the labor and difliculty of bringing them into locked register. I avoid all that and dispense entirely with. slots and lugs, by making the crown and locking rim in one piece with each other and with a connecting strip, all integral, the strip being bifurcated for a part of its length, each leg of the bifurcation being integrally connected with an edge of the transversely sectioned locking ring, hencewhen these edges are brought into overlapping register, the integral connecting strip not only looks the divided rim to the crown portion but detachably maintains the overlapping edges of the ring in locked position.

In the accompanying drawings illustrating my invention: Figures 1, 3 and 5 are respectively sections, partly in elevation, of the cap in the three stages of its formation; and Fig. 6 an elevation of the completed cap ready to be secured on the bottle head. Fig. 2 is a plan view of the cap-blank shown in Fig. 1. Fig. 4 is a plan of the cap-blank, in the next stage, as shown in Fig. 3; and Fig. 7 is a plan of the finished cap of Figs. 5

Fig. 8 is an elevation partly in section, showing the annularly-shouldered bottle and my cap secured in place thereon. Fig. 9 is an elevation of the bottle and flanged crown portion of the cap, after the additional rim has been removed therefrom; and Figs. 10 and 11 are respectively elevation and plan views of 1 ment.

-While it is necessary, with bottles applied to such uses,

to make a comparatively tight seal, it is most desirable that the cap employed for the purpose should be of such character as to be easily removed manually and without the necessity for employing a cap-removing tool, and these two desiderata my bottle-sealing device accomplishes. The bottle, of the class referred to, and having the annular shoulder below the lip, as shown in the drawing, is very common and therefore need not be further described; but I will now describe the cap ele- It is made of thin sheet metal, such as workable tin, capable ofloeing formed by stamping-up dies in a press.

As illustrated in Figs. 1 and 2, the first action of the dies is to cut out the blank, consisting of the disk-like crown 2 having a shallow annular flange 3 which is continuous and unbroken except where it is slitted to form the upper portion of a bifurcated connecting strip 10 hereinafter described; an additional ring-like rim 4 which is transversely-sectioned on the line 5, the sectional cut removing a portion of the metal as indicated at 6; and the cutting portion of the dies also removing all the metal at 7 between the flange 3 of the crown and the additional ring-like rim 4, except the two narrow strips 8, 8, between said elements, each of these strips, which are the lower and divided ends of the bifurcated strip 10, integrally connecting the flanged crown with a sectioned portion of the rim 4 immediately adjacent to the edges of the sectional cut in said rim.

As indicated in Figs. 3 and 4, the next action of the dies is to force the flanged crown downwards, within the ring-like rim 4, slightly below the upper edge thereof and bending the latter inward over the crown 2; and also decreasing the circumference of the rim 4 so that its narrower sectional edge will overlap the other, edge; while the same or next succeeding action of the dies brings the connecting strips 8, 8, one under the other and both to be bent at the center and project outwardly, as best seen in Fig. 4, and forming what is ultimately a manually detachable piece 10 of metal, said piece being, in the finished cap, bent downward, as seen in Figs. 5, 6 and 7 against the side of the ring-like rim 4 and in the same vertical plane therewith, and forming what is practically a retaining clamp, integral with both crown and retaining rim, overlying the major portion of the overlapping edges of the sectionally-divided retaining rim 4, as seen in Figs. 5 and 8, and holding them, initiall, in overlapping and locked position relatively to the crown portion of the cap. So finished the cap is preferably supplied with a cushioning disk 9, adapted o rest on and over the lip of the bottle-head (see Fig. 8) and the lower edge 12 of the ring-lilte rim 4 is then bent under such shoulder, as commonly done by well known bottle capping machines, in order to lock the cap onthe bottle-head.

To remove the cap the narrow bent connecting piece 10 is to be manually bent up again into the position shown in Fig. 4, that is to say into a plane parallel with the crown, and, with one or two bendings,-manually, is readily detachable, with the result that the sectioned ring-like rim 4 will spring apart as shown in Fig. 11, and be no longer held in locked position on the bottle-head, but readily removable by hand, leaving the flanged crown merely resting, unsecured, on the bottle lip, as seen in Fig. 9, and as readily removable therefrom manually.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 2- 1. A metallic sealing cap formed from a single piece of metal, comprising a dislclike crown portion and a trans versely-divided annular retaining rim therefor, with a bifurcated strip integrally uniting said crown portion with the respective coinciding edges of the divided retaining rim, and bent to detachah'ly maintain.said edges in overlapping register on the head of the bottle.

:2. A metallic sealing cap formed from a single piece of metal, com-prising a disk-like crown having a depending annular flange transversely slitted to form the upper portion of a bifurcated strip integral with the crown, a ringlike retaining rim having an inturned flange overlying the annular edge of the crown, said rim being transversely sectioned peripherally and with the sectional edges thereof overlapping, and each integrally connected with the respective divided ends of said bifurcated crown strip, said strip being then bent upon itself to form a retaining clamp adapted to be again bent against the overlapping sectioned edges of said retaining rim.

3. A sealing device comprising a flanged crown, an encircling flanged rim sectioned at a point in its periphery with one edge of the sectional cut overlapping that of the other, a pair of contiguous connecting strips proceeding from the flanged crown, and each of which is connected to a section of the divided rim, said connecting strips being then brought into overlapping coincidence and bent to form a single strip against the side of and parallel with the exterior rim element of the cap.

4. A sealing device comprising a metallic cap in combi-' nation with a bottle having an annular projecting shoulder below the lip, said cap being composed of two sections, namely a flanged crown, a flanged rim surrounding the crown, said rim being transversely sectioned peripherally, detachable connecting strips between the crown section and each edge of the divided rim section, and the latter bent at its lower edge under the shoulder of the bottle; substantially as described.

In testimony whereof, I have hereunto afii-xed my signature this first day of May, A. D. 1907.
